Steps to a successful mobile web business

Hello Warriors, any guru's want to share their knowledge in the mobile app industry? I am interested in creating a mobile web design company, and need some advice.

Can you guys give your thoughts on the steps to be successful in this industry?

below are some questions that I have so far

1) I noticed companies like dudamobile.com and gomobi.info offer resseller options, does it make sense for me to be a reseller? and have different packages like they do? or should i just do everything by myself?

2) is it better to charge the customer in a monthly basis or a one time fee for creating the mobile web?

2a) what are you guys charging?

3) I also noticed a lot of mobile web designing companies also offer marketing, texting marketing, qr codes. do you think it is worth providing all these services?

4) Is sms marketing a good industry to tap into?

5) how can i get a simulator on my site? I looked everywhere and can't find anything. I found this link on the forum Iphone mobile simulator emulator and was looking at the code, it does not seem very difficult to have one on the site. have anyone figure it out yet? I am not so great with it.

6)what are some do's and don'ts?

Please share your thoughts and knowledge. I also hope this post can help others who are interested in this industry.
